The countries that grow the most illegal Opium are Pakistan, Burma, Thailand, and Afghanistan, which is also the worldâs top supplier of Opium. Opium can also be grown in places like Mexico and Columbia. Afghanistan accounts to over 90% of the worldâs grown Opium.
This equation, I = V / R, tells us that the current, I, flowing through a circuit is directly proportional to the voltage, V, and inversely proportional to the resistance, R. In other words, if we increase the voltage, then the current will increase.
The equivalent resistance of resistors in series is equal to the sum of each resistor: The current through each resistor in series is equal, but the voltage is not. For a more detailed explanation and practical examples, refer to the article resistors in series.
